Effect of quenching rate on the structure and stability of Co-rich metallic glasses

Effect of quenching wheel speed on the structure, magnetic properties and magnetoimpedance effect in Co64Fe4Ni2B19−xSi8Cr3Alx (x=0, 1 and 2) melt-spun ribbons

“…Also it may be noted that the ribbons, which is produced with the faster quenching rate should certain a larger amount of free volume and thus a larger interatomic distance. Since an increase in the interatomic distance may cause a decrease in magnetic properties [19]. Based on the results, it seems that the effect of induced stresses and free volume on the decrease of magnetic properties prevail over the effect of the degree of amorphicity.…”

“…The magnetic properties of amorphous ribbons are found to depend on chemical compositions, degrees of amorphicity, quenched in internal stresses and free volume [15][16][17][18][19]. It should be mentioned that effect of these parameters on magnetic properties is complex.…”

Structural modification of supersaturated BCC-Nd(Al) solid solution

“…It is a measure of the extent to which electrons are scattered in the lattice as they move in an external electric field. Electrical-resistance measurements are very sensitive to reorganization processes at an atomic level, such as the ones that occur during structural relaxation [14]. It is well known that short-range ordering which develops in solid solutions may induce an electrical-resistance increase or a decrease [15,16].…”
